We now turn our attention to the method or process embodiments of the present disclosure described in the flow diagrams of FIGS. 5-9. It is understood by those known in the art that instructions for such method embodiments may be stored on their respective computer-readable memory and executed by their respective processors. It is understood by those skilled in the art that other equivalent implementations can exist without departing from the spirit or claims of the disclosure.

FIG. 5 illustrates a flow chart of method 5000 of payment card location reporting by a mobile device 3000, constructed and operative in accordance with an embodiment of the present disclosure. When a cardholder opts into payment card 2000 tracking, card locator application 3110 tracks the presence of payment card 2000 wirelessly.

At block 5002, mobile device 3000 determines whether there are associated payment cards 2000 within wireless range. Location tracker 3112 uses antenna 3300 to poll for payment cards 2000 within its vicinity. In at least one embodiment, antenna 3300 acts as a master, using the Bluetooth standard, to transmit in the 2.4 GHz short-range radio frequency band. Bluetooth is a packet-based protocol with a master-slave structure. A payment card 2000 receives the poll, and responds as a slave, transmitting a unique identifier, which is associated with the payment card. In some embodiments, the unique identifier is a hash of the payment card's primary account number (PAN).

When the payment card 2000 fails to respond to the wireless poll, as determined at decision block 5004, an alert is sent to the cardholder indicating that the payment card is no longer in wireless range, block 5006. The alert may be displayed on the screen 3400 of the mobile device 3000, sent as an e-mail alert, a short message service (SMS) message, text-alert, telephone call, or any other alert known in the art. The alert message allows cardholders to realize that the payment card 2000 is no longer in their possession and that they can take appropriate actions to locate the payment card 2000.

When the payment card 2000 responds to the wireless poll, as determined at decision block 5004, mobile device 3000 notifies the card location server 4000 of the payment card's location via the network interface 4300, block 5008. The location of the payment card 2000 is deemed to be the location of the mobile device 3000, as determined by the GPS antenna 3800. The notification may occur via a message containing the unique identifier transmitted by the payment card 2000 along with the current coordinates of the mobile device 3000.

Note that in some embodiments, the locations of the payment card 2000 are not periodically sent to card location server 4000, but are instead stored on mobile device 3000. In such an embodiment, the last known payment card location is sent when payment card 2000 is reported lost or missing.

Moving to FIG. 6, process 6000 is a method of tracking payment card location reporting by a card tracking server 4000, constructed and operative in accordance with an embodiment of the present disclosure. At block 6002, card location tracker 4114 receives a message from mobile device 3000. The message contains a unique identifier associated with payment card 2000, and geographic coordinates. Card location database 4210 is updated with the provided information, block 6004.

In an alternate embodiment, the locations of the payment card 2000 are not periodically sent to card location server 4000, but are instead stored on mobile device 3000. In such an embodiment, the last known payment card location is received from the mobile device 3000 by card location server 4000 when payment card 2000 is reported lost or missing.

FIG. 7 is a flow chart of method 7000 of processing lost payment card location reporting by a card tracking server 4000, constructed and operative in accordance with an embodiment of the present disclosure.

At block 7002, the card location server 4000 receives a report of a lost payment card, via a lost card interface 4116. The lost card information may be received by any method known in the art, including, but riot limited to: a telephone call from the cardholder, electronic mail, text message, disclosure to an application on a mobile device 3000, electronic entry by a customer service representative, or any other method known in the art. Usually, when a card is lost, the cardholder may provide the primary account number of the lost card, their name, government identification number, or other identifier.

At block 7004, card location tracker 4114 retrieves the last known location of the lost payment card 2000 from the card location database 4210.

In embodiments where the locations of the payment card 2000 are not periodically sent to card location server 4000, but are instead stored on mobile device 3000, card location tracker 4114 queries mobile device 3000 for the known location of the payment card 2000.

The card location database is updated, block 7006 so that the status of the lost payment card is designated in some manner as “lost” with a last known location.

Using the last known location and lost card database 4230, card location tracker 4114 generates a local lost card database 3210 for mobile devices that are proximate to the last known location, block 7008. For example, suppose the last known location of a missing payment card is in Times Square, in New York City. Mobile devices within a quarter or half-mile radius may be deemed as proximate. A lost card database 3210 may be a list or other data structure of all lost cards where the last known location is a half-mile radius from Times Square. In some embodiments, the lost card database 3210 may be a partial list of lost cards.

The determination for mobile devices that are proximate to the last known location may vary depending upon the population density of the last known location. Typically, when an area has a high population density, the radius chosen may be smaller than an area with low population density. For example, if the last known payment card is in a rural or sub-urban area, the radius of “proximity” may be larger.

The card location tracker 4114 transmits the local card database 3210 to the mobile devices 2000 that are proximate to the last known at block 7010.

FIG. 8 illustrates a flow chart of method 8000 of lost payment card location reporting by a mobile device 3000, constructed and operative in accordance with an embodiment of the present disclosure.

At block 8002, a mobile device 3000 receives a local lost card database 3210 from card location server 4000. As discussed in method 7000 above, the local lost card database 4230 is a list or other data structure of the lost cards where the last known location are proximate to the current mobile device 3000 location.

The mobile device 3000 polls for the presence of payment cards 2000, block 8004.

If no lost card is detected, the process flow returns to block 8004.

If a lost card is detected, as determined at block 8006, the mobile device 3000 notifies the card location server 4000 of the lost card location based on the mobile device's current position, block 8008.

FIG. 9 illustrates a flow chart of method 9000 reporting lost payment card location to a cardholder by a card tracking server, constructed and operative in accordance with an embodiment of the present disclosure. Once a lost payment card's location has been reported to the card location server 4000, block 9002, the payment card's location is updated in the card location database 4210, block 9004. Mobile devices 3000 that are proximate to the new location are alerted with an updated local lost card database 3210, block 9006.

At block 9008, the lost the card location server 4000 reports the location information to the cardholder by any method known in the art, including via an automated telephone call from the card location server 4000, electronic mail, text message, disclosure to an application on a mobile device 3000, or any other method known in the art. The cardholder may then use that information to find their lost payment card 2000.

The system continues to track the lost card until the payment card is reported found or cancelled by the cardholder, block 9010.
